4.0 ADJUSTING THE WORKING DEPTH
The working depth can be adjusted by turning the top rod.
When the top rod is turned and, consequently, shortened the machine will incline forwards,
setting the seeding depth lower.
This works when the ground to be tilled is soft enough to be cut to obtain the correct seeding
depth.
The correct seeding depth can be achieved by, among other things, filling the rear roller with
water.
@ If the rear roller is filled with water, empty it before it starts freezing.
5.0 SETTING THE SEED-QUANTITY
The seed quantity can be set on the Overseeder
by using
various change gears.
These provide various combinations for a
broad range of settings (see Tab 1).
The gears have been marked with a number
given in Tab. 1; by changing the gears
as indicated, the required
quantity setting is obtained.
The different combinations of gears have been installed in
the seed tray.

These quantities are determined with a slit distance of 0.3 mm between the seeding roller
and the pressure plate (see section 15.0 for setting).
In practice the quantities described in Tab. 1 may deviate to some extent due to other
measuring/working conditions.
@ In order to determine exactly the right seeding quantity for the seed used, it is
recommended to carry out a spreading test (see section 15.2).

11
6.0 TRANSPORTING THE OVERSEEDER
The user is responsible for the transport of the Overseeder behind the tractor when travelling
on public roads. Check the national traffic rules. In view of the weight of the Overseeder, a
maximum speed of 20 km/h (12.4 mph) should be observed while driving in open fields with
the machine raised. Higher speeds may endanger the driver and/or other people and even
damage the machine.
* When the machine is in the raised position, at least 20% of the weight of the
tractor should be supported by the front axle.
7.0 DRIVING SPEED
The driving speed is limited to 12 km/h (7.5 mph).
Higher speeds are not recommended in view of excessive wear and damage that may occur
to the machine due to, for example, rocks in the ground.
8.0 GENERAL REMARKS ON THE USE OF THE OVERSEEDER.
Some general remarks/tips on the use of the Overseeder.
@ A field can be tilled 2 or 3 times in different directions in order to obtain a higher
seeding density and for seeding in a diamond shape.
@ Do not make sharp turns, preferably drive in straight lines to avoid damaging the
machine and/or the ground.
@ When hitting a hard object in the soil, the cutting elements may be
burred/damaged. Try to file burrs away or replace the cutting element.
@ When the cutting elements become wet, the seed may stick and accumulate
between the cutting elements.
@ Make sure the cutting elements do not become wet or postpone the work.
@ NEVER drive backwards while the running wheel is on the ground.
9.0 OPERATING THE OVERSEEDER
Before using the Overseeder in the field, check the following:
1. Are there any loose objects in the field? Remove these first.
2. Are there any slopes? The maximum slope this machine can work on is 20
degrees.
Always work downhill.
3. Does the ground contain hard objects? If so, use the Overseeder at a low speed
and adjust the working depth.
4. Is there any danger of flying objects, such as golf balls, which may distract the
attention of the driver? If so, do NOT use the Overseeder.
5. Is there any danger of sinking or sliding away? If so, postpone the work.
6. If the soil is frozen or very wet, the work should be postponed until the conditions
are more favourable.

12
10.0 STARTING/STOPPING PROCEDURE
Before starting the seeding, check the machine for the following points:
* While checking the machine/tractor combination must be fully locked to prevent it from
driving/sliding/sinking away. The tractor engine must be switched off.
Check the seeding elements for damage and repair if necessary.
Check if the passage to the seeding elements is not blocked (e.g. funnels).
Check if the machine is not wet or moist, in particular the seeding device.
Check the seed spreading by rotating the running wheel 1 time
(counterclockwise).
Check if the drive is running smoothly.
Check the tyre pressure.

15.0 ADJUSTING THE SEEDING SLIT OPENING
Fig. 9
If the seed production does not correspond with the table, the seeding slit may need
adjustment.
This is done as follows: (see fig. 9)
1. Loosen all lock nuts 3.
2. Adjust bolt 4 such that a feeler gauge of 0.3 mm (0.012”) can be slit just between the
roller 1 and the adjustment plate.
3. Check all bolts 4 and calibrate the slit opening between roller 1 and adjustment plate
2 along the entire width of the machine to 0.3 mm (0.012”).
4. Turn roller 1 half a turn and measure the slit opening.
If necessary adjust it to 0.3 mm (0.012”) by turning bolt 4 in or out.
5. Tighten the lock nuts 3.
@ The split opening should be equal along the entire width of the roller.
@ The slit opening must have the same size as the smallest seed part. This opening is
default set to 0.3 mm.
15.1 ADJUSTING THE SEED-TRAY SCRAPER
When the seeding tray is spoiling seed, the scraper setting may be incorrect.
To adjust this, proceed as follows (see fig. 9):
1. Loosen bolts and nuts 6.
2. Move scraper 5 up or down until the correct setting has been obtained.
3. Re-tighten the bolts and nuts 6.
@ The distance between roller 1 and scraper 5 is default set to 0.8 mm and should be
equally set along the entire width of the roller.

17
15.2 SPREADING TEST
If the seeding device needs recalibration for a certain seed type or if it must be
checked for proper operation in accordance with the seed table (see section 5.0 Tab
1) a spreading test is to be carried out.
This is done as follows: (see fig. 10).
Fig. 10
1. Place the machine safely on the support legs on a level surface.
* Lock the machine to prevent it from moving.
2. First of all check the seeding slit opening for correct setting (see section
15.0).
3. Put the seed that is to be calibrated into the seed tray (4) and spread it
equally over the tray.
4. Remove the spreading tray 1.
5. Remove pins 2 on both sides of the machine.
6. Remove the funnel tray (3).
7. Slide the spreading tray underneath below the seed tray (4).
8. Turn the wheel (5) 13 full rotations counterclockwise.
9. Weigh the seed that is collected and multiply this by 5.37 (1275)
Weigh the seed that is collected and multiply this by 4.08 (1575)
Weigh the seed that is collected and multiply this by 3.06 (2075).
The result is the weight of the seed that is seeded per (kg) 100m2 / (lbs)
1000 ft2.
Compare the results with Tab. 1 (section 5.0) and do another spreading
test if necessary.
10.If the results of the spreading test do not reasonably match the calibration
values, check the seeding slit opening and adjust this if necessary (see
section 15.0).
11.Remount the parts in reverse order.
